sonnes What l claim, as new, is l y l. In a-dredging apparatus, the combination of a, duct, a head mounted upon the trally through said head andinto the duct,

and jets projecting into and around said nozzle, as and for the purpose set forth.

3. ln a dredging apparatus, the combination with a tu )port, 4of a duct having an entrance and-a ischarge end, a head mounted at the discharge end, a'nozzle carried in the head and extending from its bottom into the lower end ofthe duct, said head being provided with a chamber around the upper end of the nozzle, jets projecting into said nozzle, and a jet mounted in the chamber and mounted to direct va discharge into the duct around the upper end of the nozzle.

4. ln a dredging apparatus, the combination with a su port, cfa duct'having an entrance and a cischarge end, a head mounted at the entrance end, a nozzle carried in the head and extending romits bottom into the lower end ofthe duet, said head being provided with a chamber around the upper end of the nozzle, means for projecting a iiuid under pressure into said nozzle, means surrounding the nozzle Within the chamber for projecting a fluid under pressure into the duct around the nozzle, and means for submerglng the head and duct.

5. in a dredge, the combination with a duet and exterior pressure iluid supply ducts, of a head having a ta )ered nozzle emptying into the first duct an having its Haring end `toward the bottom, and means mounted in the nozzle and connected with the proper fluid pressure supply ducts for inducing a" current in the nozzle toward the first duct.

6. ln a dredge, the combination With a duct andexterior pressure luid supply pipes, of a head having a tapered nozzle emptying,r

rinto theduct and. having its Haring end toward the bottom of the head, and means mounted in the nozzle and connected with the pipes for inducing a current in the nozzle toward the duct. 1

' 7, In a dredge, the combination with a duct andl exterior pressure fluid supply pipes, of a bead having a tapered nozzle emptying into the duct and having its 'Haring end toward 'the bottoni ot' the head,A means mounted in the nozzle and connected With the pipes for inducing a current in the nozzle toward the duct, and means within the head .and exterior of the nozzle connected with the proper pipes for inducing a current around semelle the protruding end of the nozzle within tlie duet to ssist the other indue-ing currents.

ln u dredge, the Combination with e duet and exterior pressure .tlni supply pipes, of e heed having e, tapered nozzle emptying into t-lie duct and having its 'Hering end toward the bottoni, and ineens within the heed and exterior of vtlie nozzle connected with Elie proper pipe for inducing a. current around the protruding` end o'I1 the nozzle Within vthe d u et.

9. ln a dredge, the combination with e duet and exterior'pressure lilnid supply ipes, of e, liend, a. tapered nozzle in the lien lizwing its reduced end toward the duet, and. two oppositely arranged jets-in the nozzle intera mediate of the nozzlefs `ends and in communication with two of the pipes, so es to project the luid into the nozzle.

10. In e dredge, the combination with e duet and exterior pressure iluid supply pipes, of a head, e tapered nozzle in the heed. having its reduced end toward the duet, t-wo oppositely ,disposed jets mounted in tlie nozzle intermediate otite ends, sind in communicetion with two of4 the pipes so ae to projeet tlie fluid into the nozzle, and en auxiliary inducing jet mounted to project its fluid into the duet around the reduced end of the nozzle.

ll. lin :i dredge, the combination with e -ggeriggne duet and pipes for supplying pressure V lluid so es to enter the lower end of tlie duet to induce currents wliieli lift t'lieir'ewitli the heavier material deslred to be reniover'i, oi L heed Secured to the duct and. pipes and erried ln* the doet, e nozzle cerried by tl'iel .1 ured to the duet end pipes and carried by 'the duet, e nozzle .mounted in the heed and having e tapered end of lesser diameter than tlie dec-tv end projecting slightly into tlio lower end thereof to forni en annuler space between tlie duet and nozzle, jets connected with tlie pipes end mounted so es to empty into the nozzle, end another exterior of the nozzle end eenu neeted to one of the pipes to projeet pressure fluid through the annular peice bet-Ween elle nozzle and duet.
